Application led August 10, 1929. Serial No. 885,014.

This invention relates to a piling mechanism and more particularly to amechanism for piling a sliver of fiber as it comes from a ber workingmachine.

The receiving and piling mechanism is adapted for use in connection withany and all types of machines for working various kinds of fiber whichmay be of any composition such as animal or vegetable.

The piling mechanism is particularly adaptable for use in handlingslivers in va.- rious forms, from or to, carding machines, drawingmachines, roving machines, spinning machines, twisting machines andother well known types of fiber working machines.

The invention provides for forming a particularly compact pile of sliverof fiber which may be removed as a. unit without substanial deformation.The twist of the fiber is neutralized during piling so that it may beremoved from the pile in an untwisted condition without requiringspecial care or attention.

This is accomplished by feeding a sliver il of iiber to an oscillatingtable and imparting a predetermined wave to the liber so that it fallsin the form of eccentric, slightly curved chords which are folded backand forth across the table. The wave is impartr ed to the sliver in sucha direction that the folds or chords are of uniform length andcompletely fill the table so that the finished pile has an even contourand'is in compact form.

The invention also consists in certain new and original features ofconstruction and combinations of parts hereinafter set forth andclaimed.

Although the novel featureswhich are believed to be characteristic ofthis invention will be particularly pointed out in the claims appendedhereto, the invention itself, as to its objects and advantages, the modeof its operation and the manner of its organization V' may be betterunderstood by referring to the nism;

Like reference characters denote like parts in the several figures ofthe drawings.

In the following description and in the claims parts will be identifiedby specific names fork convenience, but they are intended to be asgeneric in their application to similar parts as the art will permit.

Referring to the drawings more in detail the invention is shown asapplied to a piling-` mechanism which may be employed in connection withber working machines 10 of any and all types. Each sliver 11 leavingliber working machine 10 is illustrated as formed Vfrom a pair ofslivers 12 which are taken from rolls or piles 13. It is obvious,however, that any number of slivers may be operated on by the fiberworking` machine and used to produce slivers 11 which are lto be piledin accordance with the present invention.

Referring more particularly to Figs.` 1 and 2 the invention is shown asapplied to receivers 14 whichl are adapted 'to receive slivers 11 whichare directed by spouts l5 thereto. Receivers 14 comprise rotary tableswhich are mounted for rotary movement onshafts 21 and U-shaped shields22 which partly enclose said tables and serve to conline the sliversduring the piling operation.

VChutes 15 (Fig. 2) are pivotally mounted as Vat 25 on the frame 26 ofthe ber/working machine. Said frame also supports driving shaft 27carrying a plurality of feed rolls 28. Shaft 30 is journalled in bracket31 secured in framey 26 and carries a plurality ofV goscillate abouttheir' centers.

presser rolls 32 which are in engagement with the various feed rolls 28.Cooperating gears 33 and 34 on shafts 3() and 27 respectively cause thenecessary rotation of rolls 28 and 32 for feeding the slivers 11 ontochutes 15.

Shaft 27 terminates in a beveled gear 35, cooperating with a beveledgear 36', carried by shaft 37 which is journalled in suitable bearingssecured to frame 26. Gear 38 carriedfby shaft 37 drives the gear 39which in turn causes rotation of crank 40. Crank 40 (Fig. 6) is providedwith a pin 41 on which is mounted connecting rod 42 which is alsopivoted to reciprocating rod 43. Rod43 isv provided with a plurality ofpins 44 (Fig. 7) carried on brackets 45 which are adjustably secured tosaid rod 43 by means of bolts 46. elongated slots permitting transverseadjustment of bracliets 45 to permit proper alignment of pins 44.

Each pin 44 engages an elongated slot 47 in arm 48 which is secured tothe underside of a chute 15 in any convenient manner. It is to be notedthat the rotary movement of crank 40 causes reciprocating movement ofrod 43 which through arms 48 causes a similar reciprocating movement ofchutes 15 about pivots 25.

Chutes 15 may also be provided with hori- Zontal pivots 50 (Fig. 2) bymeans of which their angles of inclination may be varied as desired. l Y

The lower end of shaft 37 is provided with a worm 51 (Fig. 4)cooperating with a worm gear 52 carried on shaft 53 (Fig. 2), which alsocarries sprocket 54. Chain 55 (Figs. 2 and 5) to which connecting rod 56is secured as by pin 57, is passed over sprocket 54 and idler sprocket58. Connecting rod 56 is pivf otally connected to rack 59, which engagesgear wheels 60, meshing with gears 61 which are mounted on shafts 21.

It is to be noted that the rotary movement of shaft 37 causes chain v55vto pass over sprockets 54 and 58 in the direction of the arrow'of Fig.5 and through connecting rod 56 causes oscillatory movement of rack 59.This rack drives Agear wheels 61, shafts 21 and tables 2O therebycausing said tables'to ship ofthe various' gears is preferably so chosenthat tables 20 oscillate through an angle of 360", although other anglesof oscillation may be selected if it is found desirable in aparticularcase.

In the operation of the above describedV mechanism slivers 11 are fedover chutes l5 by the action of feed rolls 28 and presser rolls 32. Theslivers are given an oscillatory motion in the direction of theirgreatest width by the oscillatory motion of the .chutes whereby they aredeposited on tables 20 in the form of folded waves. Tables 20 are slowlyoscillated Yas the slivers are fed thereto. Hence the waves areprogressively dis- The relationf placed about the periphery thereof andtake the form of eccentric, slightly curved chords. Any twist whichoccurs in the fiber while the table is turning in one direction isneutralized by a corresponding reverse twist as the table rotates in theopposite direction.

Since the wave motion is imparted to the sliver in the direction of itsgreatest width, the natural stiffness of the sliver in this directioncauses themotion to be transmitted uniformly tothe material adjacent thepile whereby the chords are formed of substantiallyequal length and asmooth contour is imparted tothe pile. In addition, the pile containsthe maximum amount of fiber per unit of volume.

The rates of movement of tables 20, chutes 15 and feed rolls 28 are sorelated that, as the sliver is fed down a chute 15, it is piled on therevolving table in the desired form and the folds are caused to extendover substantially the entire table. It is to be noted that as the pilerises the sliver becomes displaced toward the center of the table due tothe decrease in length of the unsupported section, thereby causing thehole between the various chords, which are shown in Fig. 3, toprogressively decrease in size toward the top of the pile.

The pile of sliver thus formed is composed of alternate folds extendingin opposite directions with the twist of the various folds soneutralized that the sliver may be withdrawn from the pile and appliedto any desired machine, in an untwisted condition without requiringattention. It is of comparatively regular contour and possessessuficient strength to permit removal as a unit without danger ofbecoming deformed or en tangled.

"While certain novel features of the invention have been shown anddescribed and are pointed out in the annexed claims, it will beunderstood that various omissions, substitutions and changes in theforms and details of the device illustrated and in its operation may bemade by those skilled in the art without departing from the spirit ofthe invention. It is obvious that in certain types of work the chuteconstructed in accordance with the present invention may be employedwith other types of tables and that the extent and speed of theoscillations of the table may be varied as required. In certaininstances where the twist of the fiber is of less importance acontinuously rotating table may be desirable.

What is claimed is:

1. In apiling mechanism, a rotary table. means for causing oscillatorymovement thereof, a chute for directing a sliver on said table, andmeans for oscillating said chute about a substantially vertical axiswhereby the sliver is automatically oscillated in a direction of itsgreatest width as it is fed to IOL the oscillating table and is causedto be piled in a series of eccentric chords of substantially. uniformlength, the relative movement of the chute and table being such thatsuccessive chords are angularly displaced and disposed on the same sideof the axis of the table in a substantially toroidal formation made upof a plurality of alternately superposed helices.

2. In a piling machine including a plurality of chutes, a plurality ofrotatable tables, a gear associated with each of said tables, a rackcooperating with said gears and means for causing an oscillatorymovement to said rack comprising an endless chain, a connecting rodpivoted on said chain and secured `to said rack and means for causingcontinuous movement of said chain.

3. In a piling mechanism, a table mounted for rotary movement about itsaxis, means for causing oscillatory movement of said table about saidaxis, a chute for directing a sliver onto said table and means foroscillatin said chute in a direction of the greatest Wi th of saidsliver, said oscillating chute and said oscillating table being sorelated that the sliver is fed onto the table and piled thereon in aserious of eccentric chords of substantially uniform length, successivechords being angularly displaced and disposed on thek same side of theaXis of the table whereby a substantially toroidal formation is obainedmade up of a plurality of alternately superposed helices and the twistof the various portions thereof is neutralized whereby the sliver may beremoved in an untwisted condition.

4. The method of piling a continuous sliver which comprises feeding saidsliver onto a platform at a uniform rate while imparting to said sliveran oscillatory motion inthe direction of its greatest width andsimultaneously causing said platform to oscillate about its axis wherebysaid sliver is piled in a series of eccentric chords of substantiallyuniform length, successive chords being angularly displaced and disposedon the same side of the a-Xis of the table whereby a substantiallytoroid formation is obtained made up of a plu` rality of alternatelysuperposed helices and the twist of the various portions thereof isneutralized whereby the sliver may be removed in an untwisted condition.

In testimony whereof I have hereunto set my hand.
